At present, a Bluetooth chip of an intelligent lamp is usually arranged separately from a power supply, and the Bluetooth chip is arranged in the intelligent lamp as an independent module. Therefore, the LED chip can be driven to work only by using the Bluetooth chip and the driving power supply in the intelligent lamp.
The Bluetooth communication technology is rapidly developed, the Bluetooth communication technology standard is also rapidly updated, the Bluetooth 5.0 technology standard is the latest Bluetooth technology standard proposed by the Bluetooth technical alliance in 2016, compared with the Bluetooth 4.2 technology standard, the data transmission capacity of the Bluetooth 5.0 technology standard is improved by 800%, the transmission distance is improved by 4 times, the number of bytes which can be broadcast is greatly increased, the indoor and outdoor positioning capability is enhanced, and a large amount of information can be transmitted to other compatible devices under the condition that real connection is not established. The bluetooth Mesh technology can support up to ten thousand nodes in a single network, and the bluetooth Mesh technology forwards information in a controllable flooding mode, and forwards the information from a certain node in the network to a destination node.
However, these communication technologies are not combined with bluetooth power, i.e., they are completely implemented by a bluetooth chip. If long-distance data transmission is required to be achieved through the Bluetooth mesh technology, a large number of intelligent lamps are often required to be arranged in an area, a Bluetooth power supply cannot be used as relay equipment for Bluetooth communication, the use of the Bluetooth power supply is limited, and the cost of long-distance data transmission is increased.

Detailed Description
The control method of the intelligent lamp is applied to the intelligent lamp, the intelligent lamp is provided with a driving power supply, and preferably, a Bluetooth chip, a controller and a constant current power supply are arranged in the driving power supply. Preferably, a processor and a memory are arranged in the controller, the memory stores a computer program, and the processor implements the control method of the intelligent lamp by executing the computer program.
Intelligent lamp embodiment:
the intelligent lamp of this embodiment is an intelligent lamp with bluetooth communication capability, and the intelligent lamp has an LED chip and a bluetooth power supply, see fig. 1, and the bluetooth power supply is provided with a bluetooth chip 11, a controller 12 and a constant current power supply 13. The bluetooth chip 11 is used for receiving communication data sent by an external device, and the external device may be a terminal device such as a smart phone, or an intelligent lamp, as long as the external device has a bluetooth chip and can send a bluetooth signal. In addition, the bluetooth chip 11 may also transmit the received communication data in a broadcast manner, that is, broadcast the received communication data again, so that the bluetooth chip 11 may be a relay device for transmitting the communication data.
The bluetooth chip 11 has its own unique address, and if the address information in the communication data matches the address information of the bluetooth chip 11 itself, it indicates that the currently received communication data is communication data for controlling the current smart device, and the bluetooth chip 11 sends the received communication data to the controller 12. The controller 12 may be a single chip microcomputer with data storage and data processing capabilities. After receiving the communication data sent by the bluetooth chip 11, the controller 12 obtains a control instruction in the communication data, for example, an instruction for adjusting the light emitting brightness of the LED chip, adjusts the duty ratio of the output pulse modulation signal according to the control instruction, and outputs the pulse modulation signal to the constant current power supply 13.
The constant current power supply 13 outputs stable current to the LED chip, and since the light emitting luminance of the LED chip is related to the current flowing through the LED chip, the larger the current flowing through the LED chip is, the larger the light emitting luminance of the LED chip is, and the smaller the current flowing through the LED chip is, the smaller the light emitting luminance of the LED chip is. Therefore, the light emission luminance of the LED chip can be adjusted by adjusting the duty ratio of the pulse modulation signal output by the controller 12.
Referring to fig. 2, a single chip microcomputer U5 and a bluetooth chip U6 are arranged in the bluetooth power supply as controllers, an IO port of the bluetooth chip U6 is connected with a pin of the single chip microcomputer U5 and outputs a digital signal, and another IO port of the bluetooth chip U6 is connected with another pin of the single chip microcomputer U5 and is used for receiving the digital signal output by the single chip microcomputer U5. After receiving the digital signal output by the bluetooth chip U6, the single chip microcomputer U5 obtains a control instruction in the digital signal, for example, a control instruction for adjusting the light emitting brightness of the LED chip, and outputs a corresponding pulse modulation signal, for example, a pulse modulation signal with a proper time length and duty ratio, to the constant current power supply 13.
Referring to fig. 3, the constant current source 13 has a connection terminal J1, and a connection terminal J1 for receiving an alternating current power source, for example, 220V alternating current power. The constant current power supply 13 is also provided with a rectifier circuit, for example, a full-bridge rectifier circuit DB1 composed of four diodes, which converts ac power into dc power and outputs the dc power. A filter circuit is further provided at the output of the rectifier circuit DB1, the filter circuit of the present embodiment includes an inductor L1, a resistor R3, and capacitors C3 and C4, the inductor L1 is connected in parallel to the resistor R3, and the capacitors C3 and C4 are connected to both ends of the inductor L1, respectively.
A constant voltage chip U7 is arranged in the constant current power supply 13, the rectified and filtered current is output to a constant voltage chip U7, and the voltage output by a filter circuit of the constant voltage chip U7 is stabilized to avoid voltage fluctuation.
The constant current power supply 13 is also internally provided with a constant current chip U1, and a pulse modulation signal output by the singlechip U5 is output to the constant current chip U1. In addition, a transformer T1 is formed between the constant voltage chip U7 and the constant current chip U5, the constant voltage chip U7 is provided on the primary side of the transformer T1, and the constant current chip U1 is provided on the secondary side of the transformer T1, so that the voltage output from the constant voltage chip U7 is output to the constant current chip U1 after passing through the inverter T1. Through the isolation effect of the transformer T1, the voltage of the low-voltage side of the transformer T1 is lower, and the situation that a human body touches the higher voltage to cause electric shock is avoided.
After the constant current chip U1 receives the pulse modulation signal output by the singlechip U5, the output current value is adjusted according to the duty ratio of the pulse modulation signal. Because the constant current chip U1 is an analog circuit, the output current has a fixed matching relationship with the duty cycle of the pulse modulation signal, and when the duty cycle of the pulse modulation signal increases, the output current of the constant current chip U1 also increases. The constant current chip U1 can ensure that the output current value is stably matched with the duty ratio of the input pulse modulation signal, and avoid the condition that the LED chip flickers due to the fluctuation of the output current. The current output by the constant current chip U1 passes through the inductors L4 and L6, is output to the connection terminal J3, and is output to the LED chip.
In addition, the constant current power supply 13 is further provided with a voltage reduction chip U4, and an input end of the voltage reduction chip U4 is connected to a voltage stabilizing circuit, in the embodiment, the voltage stabilizing circuit is connected to the secondary side of the transformer T1, the voltage stabilizing circuit comprises a zener diode Z1, and the voltage on the secondary side of the transformer T1 passes through a zener diode Z1 and is output to a voltage reduction chip U4, so that the voltage reduction chip U4 is ensured to obtain a stable input voltage.
The voltage reduction chip U4 outputs 3.3V low-voltage direct current after reducing the received voltage and provides the middle Bluetooth chip U6 and the controller U5, thereby ensuring that the Bluetooth chip U6 and the controller U5 obtain stable low-voltage direct current. In addition, the output end of the voltage stabilizing circuit also outputs signals to the constant current chip U7 through the photoelectric coupler U2, specifically, the input end of the photoelectric coupler U2 is connected to the output end of the voltage stabilizing circuit, that is, the light emitting diode of the photoelectric coupler U2 receives the voltage output by the voltage stabilizing circuit, and the photoelectric triode of the photoelectric coupler U7 is connected to one pin of the constant current chip U7 and outputs signals to the constant current chip U7. Thus, when the voltage stabilizing circuit outputs a high level signal, a signal is output to the constant current chip U7 through the photocoupler U2. Since the input terminal of the buck chip U4 is also connected to the output terminal of the voltage regulator circuit, the input terminal of the optocoupler U2 is also connected to the input terminal of the buck chip U4.
The embodiment of the intelligent lamp control method comprises the following steps:
the control method of the intelligent lamp is described below with reference to fig. 4. First, step S1 is executed, in which the bluetooth chip determines whether communication data is received, for example, determines whether communication data sent by the bluetooth chip on another intelligent terminal device or another intelligent lamp is received, and if no communication data is received, the bluetooth chip continues to wait for receiving communication data. If the communication data is received, step S2 is executed to acquire address information in the communication data. Since the communication data has a prescribed format, the bluetooth chip acquires address information from a preset position of the communication data according to the prescribed format.
In this embodiment, the data length of the communication data is 255 bytes at most, so that the communication data can carry a large amount of information, for example, a plurality of control instructions for the smart lamp, such as an adjustment instruction of the light emitting brightness and the color temperature.
Next, step S3 is executed to determine whether the address information acquired from the communication data matches the address information of the bluetooth chip itself. Since each bluetooth chip has its own unique address information, in step S3, the bluetooth chip compares the address information obtained from the communication data with its own address information, determines whether the two are the same, and if the two are different, it indicates that the current communication data is not the control information for the current intelligent lighting fixture, and therefore, step S9 is executed to broadcast the received communication data, that is, to the surrounding bluetooth devices. In this way, the surrounding intelligent luminaires will receive the communication data and continue transmitting to the surrounding intelligent luminaires. Therefore, each intelligent lamp can be used as relay equipment for communication data transmission of other intelligent lamps, and long-distance transmission of communication data can be achieved.
If the address information in the communication data matches the address information of the bluetooth chip of the intelligent luminaire itself, indicating that the currently received communication data is the control information for the current intelligent luminaire, step S4 is executed. The intelligent lamp sends the received communication data to the processor, preferably, the signal that bluetooth chip received is analog signal, and the bluetooth chip exports to the controller after with analog signal conversion digital signal. After receiving the communication data, the controller obtains a control instruction in the communication data, where the control instruction is, for example, an instruction for adjusting the light emitting brightness of the LED chip, an instruction for controlling a change of an on-off state of the intelligent lamp, or a control instruction for changing a color temperature of the intelligent lamp.
And if the control instruction is a control instruction for adjusting the light emitting brightness of the intelligent lamp, executing step S5, and determining the brightness of the LED chip according to the control instruction, that is, the adjusted light emitting brightness of the LED chip. Since the luminance of the LED chip is related to the current flowing through the LED chip, the current flowing through the LED chip needs to be adjusted to adjust the luminance of the LED chip. Because the constant current chip U1 receives the pulse modulation signal output by the singlechip U5, and the current output by the constant current chip U1 is related to the duty ratio of the pulse modulation signal, the output current of the constant current chip U1 can be adjusted by changing the duty ratio of the pulse modulation signal output by the singlechip U5, so that the brightness of the LED chip can be adjusted.
Preferably, after determining the light emitting brightness of the LED chip, the controller performs step S6 to determine the current flowing through the LED chip according to the light emitting brightness of the LED chip, for example, by looking up a table, and performs step S7 to determine the duty ratio of the pulse modulation signal output by the single-chip U5 according to the current output to the LED chip. Preferably, a corresponding table is arranged in the single chip microcomputer U5, and the corresponding table is a corresponding relation table between the duty ratio of the pulse modulation signal and the current value output by the constant current chip. After the controller determines the current value output to the LED chip, the duty ratio of the pulse modulation signal can be determined by inquiring the corresponding table. Finally, the controller performs step S8 to output a pulse modulation signal to the constant current chip, the pulse modulation signal being a pulse modulation signal of the duty ratio determined in step S7. Therefore, the constant current signal outputs matched current according to the duty ratio of the pulse modulation signal, and therefore brightness adjustment of the LED chip is achieved.
Preferably, in order to avoid abrupt change of the light emitting brightness of the LED chip, after determining the duty ratio of the transmitted pulse modulation signal, the controller needs to compare the adjusted duty ratio with the duty ratio of the current pulse modulation signal, and if the difference between the adjusted duty ratio and the duty ratio of the current pulse modulation signal is large, the controller gradually changes the duty ratio of the output pulse modulation signal instead of directly changing the duty ratio of the output pulse modulation signal. Therefore, the light emitting brightness of the intelligent lamp is gradually changed instead of suddenly changing, and the user is prevented from feeling uncomfortable.
Therefore, in the embodiment, the bluetooth chip is integrated in the smart lamp, and the bluetooth mesh technology is used for data transmission, so that long-distance transmission of communication data can be realized, and even if the distance between the controlled smart lamp and the smart phone is long, the smart lamp can be used as a relay device, and the communication data can be transmitted. In addition, due to the fact that the Bluetooth chips of the intelligent lamps are connected in a multi-point mode, even if the Bluetooth chip of one intelligent lamp breaks down, transmission of communication data is not affected, specifically, the communication data can still be transmitted through the Bluetooth chips of other intelligent lamps as relay equipment, and the reliability of communication data transmission is improved.
And moreover, the intelligent lamp is only used as relay equipment, so that the transmission of communication data can be realized only by using a Bluetooth power supply without arranging an LED chip.
